8(5-6v)=-7-v

help please :))

Answers

Answer:

V = 1 (Please mark the answer as brainliest)

Step-by-step explanation:

8(5 - 6v) = -7 - v

40 - 48v = -7 - v

40 = -7 + 47v

47 = 47v

1 = v

Answer:

v = 1

Step-by-step explanation:

Let's solve the problem,

→ 8(5 - 6v) = -7 - v

→ 40 - 48v = -7 - v

→ 40 + 7 = -v + 48v

→ 47v = 47

→ v = 47/47

→ [ v = 1 ]

Hence, the value of v is 1.

a. In Euclidean geometry, a line continues in opposite directions forever. As a result, the line will have an infinite length. How does this differ from a line in spherical geometry?

Answers

Euclidean geometry differs from spherical geometry because Euclidean geometry is used to set points by the use of plane.

What is Euclidean geometry?

Euclidean geometry is the study of geometrical shapes (plane and solid) and figures based on different axioms and theorems.

Now since Spherical geometry is the geometry of the two-dimensional surface of a sphere. In this context the word "sphere" refers only to the 2-dimensional surface and other terms like "ball" or "solid sphere" are used for the surface together with its 3-dimensional interior.

Euclidean geometry differs from spherical geometry because Euclidean Geometry are known to make use of a plane to be able to set points and lines, but Spherical Geometry are known to make use of spheres to set up points and great circles.

Thus, Euclidean geometry differs from spherical geometry because Euclidean geometry is used to set points by the use of plane.

A group of friends wants to go to the amusement park. They have $235.75 to spend on parking and admission. Parking is $6.25, and tickets cost $25.50 per person, including tax. Write and solve an equation which can be used to determine pp, the number of people who can go to the amusement park.

Answers

Answer:

The equation for the number of people is 25.50x + 6.25 = 235.75 and the number of people who can go to the amusement park are 9.

Step-by-step explanation:

We have,

Spend on parking and admission = $235.75  

Spend on parking  = $6.25

Cost of ticket per person = $25.50

Let number of number of people = x

Now,

According to the question;

25.50x + 6.25 = 235.75

So, this the equation for number of number of people.

Now,

25.50x + 6.25 = 235.75

25.50x = 229.50

x = 9

So, number of number of people is 9, which we find out using the above mentioned equation.

Hence, we can say that the equation for the number of people is 25.50x + 6.25 = 235.75 and the number of people who can go to the amusement park are 9.

The number of people who can go to the amusement park is 9 they have $235.75 to spend on parking and admission. Parking is $6.25.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

A group of friends wants to go to the amusement park. They have $235.75 to spend on parking and admission.

Parking is $6.25, and tickets cost $25.50 per person, including tax.

Let x be the number of people

6.25 + 25.50x = 235.75

25.50x = 235.75 - 6.25

25.50x = 229.5

x = 9

Thus, the number of people who can go to the amusement park is 9 they have $235.75 to spend on parking and admission. Parking is $6.25.

Keitaro walks at a pace of 3 miles per hour and runs at a pace of 6 miles per hour. Each month, he wants to complete at least 36 miles but not more than 90 miles. The system of inequalities represents the number of hours he can walk, w, and the number of hours he can run, r, to reach his goal.

3w + 6r ≥ 36

3w + 6r ≤ 90

A graph shows w on the x-axis, from 0 to 30, and t on the y-axis, from 0 to 24. Two solid lines are shown. The first line has a negative slope and goes through (0, 6) and (12, 0). Everything above and to the right of the line is shaded. The second line has a negative slope and goes through (0, 15) and (30, 0). Everything to the left of the line is shaded.
Which combination of hours can Keitaro walk and run in a month to reach his goal?

2 hours walking; 12 hours running
4 hours walking; 3 hours running
9 hours walking; 12 hours running
12 hours walking; 10 hours running

Answers

The combination of hours that Keitaro can walk and run in a month to reach his goal will be A. 2 hours walking; 12 hours running

How to illustrate the information?

From the information, Keitaro walks at a pace of 3 miles per hour and runs at a pace of 6 miles per hour. Each month, he wants to complete at least 36 miles but not more than 90 miles.

The equation is

3w + 6r ≥ 36

3w + 6r ≤ 90

The combination of hours that Keitaro can walk and run in a month to reach his goal will be 2 hours walking, and 12 hours running.

This will be:

3w + 6r ≤ 90

3(2) + 6(12)

6 + 72 = 78

Therefore, 78 is less than 90.

The correct option is A.

note: this is a multi-part question. once an answer is submitted, you will be unable to return to this part. a girl operates a radio-controlled model car in a vacant parking lot. the girl’s position is at the origin of the xy coordinate axes, and the surface of the parking lot lies in the x-y plane. she drives the car in a straight line so that the x coordinate is defined by the relation x(t)

Answers

At time t, the position is x(t) = 0.5t3 - 3t2 + 3t + 2.

What are coordinates?Coordinates are two numbers (Cartesian coordinates) or a letter and a number that point to a specific point on a grid known as a coordinate plane. A coordinate plane has four quadrants and two axes: x (horizontal) and y (vertical).

To find the position:

The derivative of x with respect to t is zero when the velocity is zero. That is to say,

x' = 1.5t² - 6t  + 3 = 0 or t² - 4t + 2 = 0

Use the quadratic formula to solve.

t = (1/2) [ 4 +/- √(16 - 8)] = 3.4142 or 0.5858 s

When t =0.5858 s, the position is:

x = 0.5(0.5858³) - 3(0.5858²) + 3(0.5858) + 2 = 2.828 m

When t=3.4142 s, the position is:

x = 0.5(3.4142³) - 3(3.4142²) + 3(3.4142) + 2 = -2.828 m

Reject the negative answer.

So, when t = 0.586 s, the velocity is zero and the distance is 2.83 m.

The second derivative of x with respect to t is zero when the acceleration is zero.

That is to say,

3t - 6 = 0t = 2

The distance traveled is:

x = 0.5(2³) - 3(2²) + 3(2) + 2 = 0

So, when the acceleration is zero, t = 2 s, and the distance traveled is zero.

Therefore, at time t, the position is x(t) = 0.5t3 - 3t2 + 3t + 2.

Answers

The combined cost of one pound of pork and one pound of beef is $ 15.5.

How to estimate the combine cost of two articles bought in a butchery

The total cost is equal to the sum of the products of unit price and quantity of an article. In this problem we find the sum of the quantities of two products (pork roast, beef roast), whose expression can be described below:

67.50 = (3.25) · (x - 0.50) + (5.5) · x

Where x is the unit cost of the beef roast.

Now we proceed to solve the equation for x:

67.50 = 3.25 · x - 1.625 + 5.5 · x

69.125 = 8.75 · x

x = 7.9

A pound of beef roast costs $ 7.9 and a pound of pork roast costs $ 7.4. Then, the combined cost of one pound of prok and one pound of beef is:

C = 1 · 7.9 + 1 · 7.4

C = 15.5

The combined cost of one pound of pork and one pound of beef is $ 15.5.

The average income,I, in dollars, of a lawyer with an age of x years is modeled with the following function:

Solving a quadratic equation, the youngest age for which the average income of the lawyer is of $250,000 is of 26 years.

What is a quadratic function?

A quadratic function is given according to the following rule:

y = ax² + bx + c

[tex]\Delta = b^2 - 4ac[/tex]

The solutions are:

[tex]x_1 = \frac{-b + \sqrt{\Delta}}{2a}[/tex]

[tex]x_2 = \frac{-b - \sqrt{\Delta}}{2a}[/tex]

In which:

[tex]\Delta = b^2 - 4ac[/tex]

For this problem, the equation that models the income as function of age is given by:

I(x) = -425x² + 45500x - 650000.

The income is of 250,000 when I(x) = 250000, hence:

250000 = -425x² + 45500x - 650000.

425x² - 45500x + 900000 = 0.

Hence the coefficients are a = 425, b = -45500 and c = 900000, then:

[tex]\Delta = (-45500)^2 - 4(425)(900000) = 540250000[/tex][tex]x_1 = \frac{45500 + \sqrt{540250000}}{2(425)} = 80.87[/tex][tex]x_2 = \frac{45500 - \sqrt{540250000}}{2(425)} = 26.18[/tex]
